The use of bioflavonoid dihydroquercetin in food products of animal origin

One of the most important tasks of a national economy is supplying population with food products made from safe and high-quality raw materials. The research was conducted jointly with dairy industry specialists at the milk processing enterprise OOO “VNIMI-Sibir”. To produce safe and high-quality raw materials, it is necessary to adhere to two basic rules: compliance with requirements to production and their constant maintenance. The first rule is responsible for granting a product its basic properties, and the second for their preservation during the shelf-life without deterioration of the product quality. To stabilize the fatty phase, dihydroquercetin (DHQ) is used, which is a natural antioxidant of bioflavonoid nature. It is able to exhibit PP-vitamin activity, which increases the nutritional value of products. As it is difficult to achieve the expected effect using one antioxidant, we developed antioxidant complexes that were able to extend the product shelf-life. They consisted of a DHQ antioxidant and a synergist, which was ascorbic acid. The dosage is 0.02 percent per kilogram of fat of the product. In addition, to increase the nutritional value of the product, animal fat was replaced with vegetable fat in a ratio of 1 : 1, which helped solve the problem of saving expensive and scarce dairy raw materials. 2 laboratory samples were developed: a dry high-fat dairy product and a dry high-fat milk-containing product. We used standard methods to determine these samples quality in fresh form and during long-term storage. Quality and safety of the samples were assessed according to a number of standardized indicators: organoleptics, physico-chemical and microbiological properties. As a result of the experiments, technologies of dairy and milk-containing products, increased nutritional value and storage capacity for general and specialized purposes were obtained, which was reflected in the development of scientific documentation (product specifications and technology regulations) for new products.
